an opening for the boss to play in, tion of the bearing which extends the free extremity of the boss being in diameter, forming a second, and smaller bearing 5, in alinement with the first hearing. This boss and hearingBconstitute the support for the transom.

The transom crank 6, having To all whom it may concern:

Be it known that I, ERNEST E. BELL, a citizen of the United States, residing at Glen Ridge, in the county of Essex, in the State of New Jersey, have invented a certain new and useful Transom-Operator, of which the following is a specification.

The object I have in view is the produc-, tion of a transom operator which may be concealed in the trim, and which will be of side view in Fig. 2 minimum depth and will thereby be locatplan View in Fig. 3, is flattened as able within many different varieties and and enters a keyway or slot 8 inthe center sizes of trim, which may be attached to the trim, by simply removing the front trim, lies outside of the boss is without removing the jamb, which will be strong and rigid, and will hold the transom is left. These from the folaccompanying a stem 7. This stem,

is provided ed by the latter.

extremity. This dewith a pin 9 on its open in the position that it and other objects will appear lowing specification and drawings.

In the drawings: Figure 1 is an elevation my invention looking toward the inside of the jamb and showing the edges of the front and rear trims, and also illustrating the position of the transom in broken lines. Fig. 2 is a section onthe line 2-2 of Fig. 1. Fig. 3 is a section on the line 33 of Fig. 1. Fig. 4 is a section on the line Hot Fig. 1, and Fig. 5 is a perspective view of the guide for the cam plate.

In all the views, like parts are designated by the same reference characters.

for rotating the transom in connection with the boss which supports it. t The crank is rotated by meansof a vertically movable with which the pin 9 This p ate moves up and down withinsuitable guideways secured to the jamb. .The shape of the plate is best shown in Fig. 5. The edges of the plate'are turned over at.

2 in order to give surface. and to impart strength to the plate. The edges of the cam slot 11 are-flanged at 13 so as to get an augumented hearing sur face for engagement with the crank pin9.

In the drawing a is the jamb; 7) is the openings in the plate, which are made for front trim; e is the rear trim; (Z is the lintel; lightness. e is the transom, and f is the front edge of The guide 14. is attached to the jamb a, the jamb. .and comprises two plates, 15 and 16. The

Only one end of the transom is shown, the plate 15 lies a 'ainst the face of the jamb 90 and is bent over the edge f of the jamb and therein. The other edge of the plate is flanged at 17, producing a. way or slot for one of the turned edges 12 of other end being/supported on the ordinary hook pintle, which is not illustrated.

The transom is supported upon a boss 1, which is formed with a base plate This plate is shown as countersunk in the end of the transom, and is attached thereto by screws as shown. The boss is cylindrical and of less length than the thickness of the jamb a. This boss turns within a bearing 3, said bearing lying within a suitable open ing in the jainb. This bearing is provided with a flange 4, which is recessed at the outer face of the jamb and secured thereto by screws. (See Fig. 2.) The bearing has cam plate from lifting, due to pressure of the crank pin, and therefore constitutes a means for preventing the pin from binding in the slot. The flange incloses the edge of the cam plate, and as it L engage the cam plate, irrespective of the position of the latter, is constitutes an offsetting means for the lateral thrust of the crank applied in line with the thrust. The

The cam plate is-adapted to be moved up and down by suitable mechanism to engage the crank pin with its'inclined slot, and thereby open and close the transom.

As the pressure on the crank is consider-. the fact that the transom is there is considerable strain plate and e bearings-of bled and put together.-

In assembling the portions of the guide and box can be taken to pieces to permit the introduction of the cam plate andgthe rack and pinion and gears.

In-accordance with the provisionsof the patent statutes I have \d'escribed the prin ciple of my invention, together with the apparatus which I now'pj nsidento represent the best embodiment thereof; but Idesire usually heavy, between the cam the transom.

In order to provide for this strain I use the following'deviee; The plate 15 is rovided with a circular opening 20. The e. ges of this opening are flanged inward, as shown in Fig. 2. This opening is adapted to surround the bearing 3 (see Fig. 2) and snugly engage therewith. This roduces a rigid connection between the guide 1a and the bearing 3, and as the connections'between the crank and transom are rigid, and the. connections between the cam plate and Having now described my invention, what I claim as new and ters Patent is 1.
